One DirectionAriana Grande5 Seconds of Summerthe WeekndDemi Lovato… let’s face it, the 2015 American Music Awards lineup was already star-packed, but lacked a certain Canadian male pop superstar. Now, that wrong has been righted: Justin Bieber is rocking the AMAs on Sunday night (Nov. 22).

tweet from the official AMAs account promises a “medley of hits” from the Biebs during the awards ceremony. Will it be his oeuvre of Purpose smashes — “What Do You Mean?,” “Sorry” and “Where Are U Now”? Maybe an older hit tossed in for fun? Perhaps a holiday banger from his 2011 Mistletoe LP? Probably not, but you can't say for certain, can you!

Bieber has been all over the tube promoting Purposeclick here for his Tonight Show take on “Sorry,” and check out his Halsey duet on “The Feeling” from The TODAY Show this morning.
